Engineers’ new approach brings images into focus

Cred­it: Whit­ing School of Engi­neer­ing Johns Hop­kins researchers have devel­oped an effi­cient new method to turn blur­ry images into clear, sharp ones. Called Pro­gres­sive­ly Deblur­ring Radi­ance Field (PDRF), this approach deblurs images 15 times faster than pre­vi­ous meth­ods while also achiev­ing bet­ter results on both syn­thet­ic and real scenes. “Often­times, images are blur­ry because aut­o­fo­cus…

Intel introduces approach to boost power efficiency, reliability of packaged chiplet ecosystems

Cred­it: Das Shar­ma et al The inte­gra­tion of elec­tron­ic chips in com­mer­cial devices has sig­nif­i­cant­ly evolved over the past decades, with engi­neers devis­ing var­i­ous inte­gra­tion strate­gies and solu­tions. Ini­tial­ly, com­put­ers con­tained a cen­tral proces­sor or cen­tral pro­cess­ing unit (CPU), con­nect­ed to mem­o­ry units and oth­er com­po­nents via tra­di­tion­al com­mu­ni­ca­tion path­ways, known as front-side-bus (FSB) inter­faces.…
